sPncIFICA'rrON forming part of Letters Patent No. 706,942, dated ingest12, 1902. Application iiled March 4,1902. Serial N0- 66.610.` (Nomodel.)

My invention relates to improvements in.

cultivators and the object that I have in view is the provision of asimple, compact, and strong machine which embodies means for the removaland replacement of a central toothed section, which also allows for thelateral adjustment of the toothedside frames, so as to cultivate bothsides of a row of growing corn, and which allows the front portions ofthe side frames to be raised and to swing free.

With these ends in view the invention conzo sists in the combination,construction, and

arrangement of parts,-whichwill be hereinafter described, and the actualscope of the invention will be deiined by the claims.

Reference is to be had-to the accompanying drawings, `forming a part ofthis specification, in which similar characters of reference indicatecorresponding partsin all the flgures. Figure 1 is al plan view of acultivator con-` 4o clamping one of the cultivator-"teethto a portion ofa tooth-carrying frame; and'Fig. 7 is a transversesection in the planeof the dotted line 7 7 of Fig. looking in the direction of the arrow.

5 designates a cross-piece provided with the depending arms 6, saidcross-piece and the arms forming a bent axle adapted to support thecarrying-wheels 7, the latter being made, preferably, of metal. Themembers forming 5o the draft-tongue 8 are united firmly at their rearends to the cross-piece 5 of the axle, and these members are disposed inthe forwardlyconverging relation shown more clearly byv pending arms 6of the bent aXles are braced by the inclined rods 14, the same extendingfrom the cross-bar 11 to the lower end portions of the arms. (See Fig.2.)

The end portions of the cross-bar 11 are extended beyond the outsidefaces of the converging meinbers S, forming the tongue, and to said endportions of the cross-bar are firmly secured the inverted- U shapedhangers 15 16, the same being more clearly shown by Fig. S of thedrawings. These hangers extend or depend a suitable distance below thecrossbar 11, as shown by Figs. A2 and 3, andl said hangers supportsuitableladjustable devices to be hereinafter described, whereby the twocarrying-frames 17 18 may be individually connected with said hangers inan adjustable manner.

The two carrying-frames 17 and 18 are preferably of the approximatelyoval shape shown by Figrl, although this particular shape of the framesis not essential, and `said frames are arranged side by side, so as tolie in substantially the same horizontal plane, the two frames being1disposed on opposite sides of the median line of the machine, asrepresented more clearly by Fig. 1. I prefer to make each tooth-carryingframe from a band or bar of metal, which is bent to the substantiallyoval form heretofore described, and to arrange the pointed or narrow endof said frame at or toward the front, thus bringing the contracted endof eachfra'me adjacent to one of the hangers 15 or 16.

The frames 17 A18 are equipped with gangs of cultivator-teeth 19, andthegang of teeth on each frame is disposed in the staggered order shown byFig. 1-that is to say, two of the teeth are arranged at the narrow frontportion, two more teeth at thewidest portion of the frame, and a numberof teeth-as, for

IOO

exam ple,four teeth-are connected to the rear portion of said frame. Theparticular number and arrangement of teeth in the 'gang on each framemay, however, be varied. Each tooth is preferably of the form shown moreclearly by Fig. 6, and it is formed from a piece of flat springmetal,which isbent to the curved shape shown in said figure, the upperportion of said spring being curved backward upon itself to form an arm20, which is equipped with an upstanding shank 21, the latter beingindicated by dotted lines in Fig. 6 and by full lines in Fig. 7.

Each tooth is connected individually and adjustably to its proper frameby means of a clamp 22, the same beingin the form of a fian ged platearranged to laterally receive the bar forming the frame adapted to carrythe gang of teeth. (See Figs. 6 and 7.) This plate of the clamp is openon one side in order to enable the clamp to be applied to the frame, andthe parts are held firmly together by the provision of a removable plate23, the latter being secured to the plate 22 of the clamp by means ofbolts 24. (See Fig. 7.) Said plate 22 of the tooth-clamp is providedwith a vertical socket adapted to receive the shank 21 of thespring-tooth, and this shank is held adjustably in the socketed clamp bya set-screw 25.

It will be observed that the clamp 22 and the tooth held therein may beshifted back and forth to variable positions on the carrying-frame, andsaid clamp may be held securely in its adjusted posit-ion by tighteningthe bolts 24, so as to firmly connect the parts 22 23 upon thecarrying-frame. At the same time the shank of the tooth may be raised orlowered in the socket, or it may be turned axially in the socket, so asto properly position the tooth in the clamp, and the screw 25 serves tobind against the tooth-shank in order to hold said tooth in its properposition. It will be understood that the adjustment of the clamp ou theframe and the adjustment of the tooth within the clamp may be effectedseparately and individually.

I will now proceed to describe the means for adjustably connecting oneof the toothcarrying frames to one of the hangers; but it will beunderstood that each frame is connected in a similar way to one hanger.Through the lower portion of the inverted-U- shaped hanger-as, forexample, the hanger 15-passes a bolt or headed rod 26, (see Figs. 4 and5,) and on this rod is loosely arranged the sleeves 27 28, the samebeing disposed between the terminal portions of the hanger 15 andserving to brace the separated ends thereof. Although I have shown twosleeves on the through bolt or rod 26, it is evident that one of thesesleeves may be omitted. A shiftable sleeve or collar 29 is arrangedloosely on the outside sleeve 28, and it is adapted to be adjusted backand forth on said sleeve 28 as may bedesired. This shiftable collar isequipped with a binding-screw 30,

adapted to impinge the sleeve 28 and to hold said collar 29 from endwiseor rotary displacement on the Vsleeve 28. The'shiftable collar isprovided with arearwardly-extending arm 31, which is embraced by asubstantially U- shaped clip 32, the legs of which are arranged tooverlap the top and bottom edges of the arm 31, as shown by Fig. 5. Thisclip and the arm of the shiftable collar are connected pivotallytogether by means of a vertical bolt 33, the same being arranged to passthrough the arms of the clip and the arm of the collar, thus permittingthe clip to turn in ahorizontal plane and on a vertical axis afforded bythe bolt 33. The front contracted portion of the tooth-carrying frame isheld or confined between the cross-bar of the clip 32 and the rear edgeof the arm 31, and said frame is thus connected by the clip and the boltto the collar 29, which is attached to the sleeve 28, that is supportedin the lower end of the hanger. The clip 32 is provided at its top edgewith a rearwardly-extending liange 34, and this flange is engaged by afinger 35 on an adjusting-arm 36.. This arm is arranged to overlap thetop edge of the U-shaped clip 32, and it is fitted loosely on the upperportion of the bolt 33, whereby said arm 36 is pivotally connected tothe clip by the bolt, and the finger of the arm engages with the flangeof the clip, so as to lift the clip and the frame which is attachedthereto. This lifting action of the arm 36 is effected and controlled bya chain 37, which is attached to the rear end of the arm, as shown byFig. 2, said chain being connected at its upper end to a crank-arm 38,which forms part of anadjusting-lever 39, the latter having a suitablelocking-pawl (not shown) adapted to engage with a notched segment 40,which is attached to the cross-piece 5 of the bent axle. It will beunderstood that one of these levers 39 is provided for each arm 36,connected to each toothcarrying frame, and this lever may be operated soas to lift the arm of the frame, whereby the front end of the frame maybe raised, so as to swing free.

-In Figs. 1 and 3 of the drawings I have shown my cultivator .equippedwith a central section, which comprises a frame-piece 41, having therearwardly-diverging arms 42, said frame-piece and its arms beingequipped with a series of the spring-teeth 19. This central section isdisposed between the ovalshaped frames 17 18, and the rear ends of thearms 42 may be attachedto or connected with said tooth-carrying framesin any suitable way. The front portion of the frame member 41 is adaptedto be connected with the hangers 15 16 by the inclined bars or braces43, (see Fig. 1,) the same extending from the frame-section 41 andattached in a suitable way to the hangers. This central frame-sectionand its teeth may be disconnected from the implement, and the two frames17 18 and the teeth thereon may be separated or adj usted laterally forany desired distance,

IIO

whereby the implement is adapted for operation on the two sides of a rowof growing corn. Inthislateraladjustmentoftheframes 17 18 the collars 29are moved endwise on the sleeves 28, which are supported in the lowerends of the hangers.

The draft appliances may be of any suitable character; but, as shown, Ihave provided the cross-bar 12 with the depending draft-bars 44, thelatter having connection at their lower ends by means of links 45 withthe hangers 15 16. The singletrees 46 are connected adj ustably in anysuitable way to the draft-bars 44. (See Figs. l and 2.)

The two sleeves 27 28 at the lower part of the hanger 15 areadvantageous, because the outer sleeve 2S is adapted to turn or rock onthe inner sleeve 27, the latter being held stationary within the hanger.The sleeve 28 may be said to be made fast with the toothed frame, in acertain sense, in that the collar 29 and the coupling 32 serve to unitethe frame and the sleeve in a manner for the latter to rock on thesleeve 27 when said fram is raised or lowered.

Each tooth-carrying frame is provided at its rear portion with a hook48, to which may be connected the chain 37, thus making provision forlifting the rear portion of the frame.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A cultivator, comprising a draft-frame havingdepending hangers, side frames connected to said hangers, a removableframesection having rearwardly-diverging arms attached to said sideframes and having a forwardly-extending arm between the side frames,draft connections attached to said arm of the removable framesection andto the hangers, and teeth secured to the side frames and theframe-section.

2. A cultivator, comprising a draft-frame having depending hangers,horizontal bolts secured in the lower parts of the hangers, rockablesleeves fitted individually on the bolts, shiftable collars tted on saidsleeves for adjustment lengthwise thereof and each having means forclamping the same fast with the sleeve to turn therewith, toothed frameshaving pivotal connection with the collars, and means for lifting saidframes.

3. In a cultivator, the combination of a hanger formed by a pair ofmembers, a horizontal bolt secured in said members of the hanger, asleeve fitted loosely on the bolt and disposed between the members ofthe hanger, a collar shiftable lengthwise on the sleeve and having aclamp for making the collar fast with the sleeve, a toothed frame, and atransverse vpivotal connection between the collar and the frame.

4. In a cultivator, the combination with a hanger-supported sleeve, of aclip having a pivotal connection with said sleeve, a bowed toothed frameconiined in said clip, and a lifting-arm having a pivotal and shiftableenA gagement with the clip.

5. In a cultivator, the combination with a sleeve, and a collar, of aclip united by a transverse pivot to the collar and having a lip oriiange, a frame attached to the clip, and a lifting-arm connected tosaid transverse pivot and shittably engaging with the flange of theclip.

6. A wheeled cultivator having a hangersupported clip, a tooth-carryingframe attached to the clip, and a lifting-arm having a pivotal andshiftable connection with the clip.

7. A wheeled cultivator provided with a hanger, a collar supportedtherein and provided with an arm, a iianged clip pivoted to said arm ofthe collar, a tooth-carrying frame confined in the clip, a lifting-armfitted to the pivotal bolt of the clip and having a linger which engageswith said clip, and means for raising said lifting-arm.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
